To answer your questions one-by-one....
1. Spray accomplishes same task as pins. I've had no problems with shifting, and have never had a wrinkle since I started using it.
2. Adhesive time varies, but anywhere from a couple of months to a year or more.
3. Spray lightly -- a little goes a long way. Spray each side of your layers (backing and batting, top and batting).
4. Adhesive washes away w/ regular washing.
5. I find the stiffness of spray basting helpful when FMQ -- I use less pressure with my hands and arms. Also helps machine and walking foot treat your quilt as one piece of fabric since they all move at the same time.
No hard and fast answers --- just been my experience.
And, I use June Tailor --- I buy all of it the day after Thanksgiving at Joann's (I pre-order it so I don't clear off the shelves). All notions are 50% off, and there's an extra 20% off coupon in the paper or mailer. That makes the price very attractive.

Some questions I have:
1. Is it as good as pin basting? Will quilt sandwich shift during MQ?
2. How long can it last without the tackiness wearing away?
3. How much do I need to spray? How many layers?
4. Can the spray be easily removed through washing? Any special detergent I need to use?
5. Noticed that the fabrics were slightly stiff after basting. Will this affect the MQ process when I use a walking or darning foot?
